Course Learning Objectives:
This course will enable students to
CLO1 To expose the students to standards and conventions
followed in preparation of engineering drawings.
CLO2 To make them understand the concepts of orthographic
and isometric projections.
CLO3__ Develop the ability of conveying the engineering
information through drawings.
CLO4 = To make them understand the relevance of
engineering drawing to different engineering domains.
CLO5_ To develop the ability of producing engineering
drawings using drawing instruments.
CLO6 To enable them to use computer aided drafting
packages for the generation of drawings.
MODULE-I
Introduction to Computer
Aided Sketching:
Introduction, Drawing Instruments and their uses, relevant
BIS conventions and standards. Lettering, line conventions, dimensioning,
material conventions, and free hand practicing.
Computer screen, layout of the software, standard tool bar
/ menu and description of most commonly used tool bars, and navigational tools.
Co-ordinate system and reference planes HP, VP, RPP &
LPP of 2D/3D environment. Selection of drawing sheet size and scale.
Commands and creation of Lines, coordinate points, axes,
poly-lines, square, rectangle, polygons, splines, circles, ellipse, text, move,
copy, off-set, mirror, rotate, trim, extend, break, chamfer, fillet, curves,
constraints viz., tangency, parallelism, inclination and perpendicularity.
MODULE-II
Orthographic projections of
points, straight lines and planes:
Introduction,
Definitions - Planes of projection, reference line and conventions
employed. First angle and Third angle projection.
Projections of points in all the four quadrants.
Projections of straight lines (located in first quadrant/first angle only),
true and apparent lengths, true and apparent inclinations to reference planes
(No application problems and midpoint problems).
Orthographic projections of plane surfaces (First angle
projection only):
Projections of
regular plane surfaces—triangle, square, rectangle, pentagon, hexagon
and circle-in simple positions inclined to both the planes; planes in different
positions by change of position method only. (No problems on punched plates and
composite plates).
MODULE - III
Projections of
solids: Introduction, definitions — projections of right regular
tetrahedron, hexahedron (cube), prisms, pyramids, and cones with axis inclined
to both the planes. (Solids resting on HP only and no problems on octahedrons,
and freely suspended solids.)
MODULE IV
Development of
Lateral Surfaces of Solids: Introduction to section planes and
sectional views. Development of lateral surfaces of right regular prisms,
cylinders, pyramids, and cones resting with base on HP only. Development of
their frustums and truncations. (No problems on lateral surfaces of trays,
tetrahedrons, spheres and transition pieces).
MODULE-V
Isometric
Projection (using isometric scale only) Introduction, Isometric scale,
Isometric projection of simple plane figures, Isometric projection of
hexahedron(cube), right regular prisms, pyramids, cylinders, cones, and
spheres. Isometric projection of combination of two simple solids. Conversion
of given isometric/ pictorial views to orthographic views of simple objects.
Course Outcomes:
Upon completion of
this course, students will be able to
CO1 Prepare engineering drawings as per BIS conventions
mentioned in the relevant codes.
CO2 Produce computer generated drawings using CAD
software.
CO3 Use the knowledge of orthographic projections to
represent engineering information / concepts and present the same in the form
of drawings.
CO4 Develop isometric drawings of simple objects reading
the orthographic projections of those objects.
CO5 Convert pictorial and isometric views of simple
objects to orthographic views.
Question paper pattern:
Module -1
is only for
practice and CIE and not for examination.
Question paper for each batch of students will be sent
online by VTU and has to be downloaded before the commencement of Examination
of each batch. The answer sheets will have to be jointly evaluated by the
Internal & External examiners.
A maximum of THREE questions will be set as per the
following pattern (No mixing of questions from different Modules).
Scheme of evaluation: From Chapters Ne
Module 2
[Choice between (Lines or Planes)] 25
Module 3 45
Module 4 or Module 5 30
Total 100
Students have to submit the computer printouts and the
sketches at the end of the examination. Both Internal & External examiners
have to jointly evaluate the solutions (sketches) and computer display &
printouts of each student for 100 marks (60 marks for solutions & sketches
+ 40 marks for computer display and printouts) and submit the marks list along
with the solution (sketches) on graph sheets & computer printouts in separate
covers.
Each batch must consist ofa maximum of 12 students.
Examination can be conducted in parallel batches, ifnecessary.
